Product Description:

The MDD090A-N-030-N2M-110PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Sold as a motor for digital drive controllers, it converts commanded current from an inverter into regulated torque and speed for positioning, indexing, or velocity-controlled axes in industrial automation cells, pick-and-place stations, and light conveying equipment. Its electromagnetic design supports cyclic operation and quick reversals, making it suitable for mid-range servo tasks where compact size and consistent dynamic performance are necessary. In closed-loop operation, the motor responds quickly to changing command values so the connected axis can maintain smooth movement during acceleration, deceleration, and repeated positioning sequences.

During continuous stall conditions, the motor produces 3.7 Nm of torque without overheating. It can accelerate loads to a nominal speed of 3000 rpm when a matching drive supplies current, giving the axis a practical operating range for indexing and speed-regulated motion. A built-in blocking brake delivers 6.5 Nm of holding torque to secure vertical or suspended axes whenever power is removed. Accurate alignment is aided by the 110 mm centering diameter, while digital servo feedback reports rotor position to the controller with high resolution for stable servo control.

The rotating parts use standard balancing, so vibration remains within normal limits when the shaft is coupled to machinery. Power and feedback connectors face Side B, which can simplify cable routing in cabinets where cables are brought in from one direction, and the motor uses a plug-in connector for electrical connection. The drive end has a keyway and a shaft seal, while the opposite side does not have a side-B shaft end. The motor also uses a 090 frame with A length and an integrated multiturn absolute encoder, which supports position tracking over more than one mechanical revolution during repeated machine cycles.
